CHARLES A. SAXE, OF PHILADELPHIA, PENNSYLVANIA.

ELECTRO-MAGNETIC MOTOR.

SPECIFICATION forming part of Letters Patent No. 298,507, dated May 13, 1884:.

Application filed September 5, 1883.

.To all whom, it may concern.-

Be it known that I, CHARLES A. SAXE, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Electro-Magnetic Motors, which improvement is fully set forth in the following specification and accompanying drawings, in which- Figure 1 is a top or plan view of the electric motor embodying my invention. Fig. 2 is a vertical section thereof in line 00 00, Fig. 1. Fig. 3 is a section of a portion in line y 3 Fig. 1.

Similar letters of reference indicate corre sponding parts in the several figures.

My invention consists of an electric motor the power whereof is adapted for the propulsion of cars, boats, locomotive and stationary engines, and vehicles generally, and the driving of machinery, &c., the construction and operation being hereinafter fully set forth.

Referring to the drawings, A represents a bed, frame, or table, on which is mounted a shaft, B, to which are keyed or otherwise secured ratchet-wheels O, of which in the present case two are shown.

D represents magnets, which are supported on the frame A, and E represents an armature therefor, which is also properly supported on said frame, and carries pawls or dogs F, which are adapted to engage with the ratchetwheels 0. To said armature Eand a proper part of the frame A is secured a spring, G, the object whereof is to retract or move the armature from the magnet when the electric circuit is broken and return the dogs F over the teeth of the ratchets C, so as to take hold thereof anew.

H represents an upright circuit-breaking arm, which is pivoted to the table A and carries at its upper end a pin, J, which projects into a slot of a link or eye, K, the latter being secured to the armature E, and connects the same with the arm H.

L represents a screw whose platinum point is adapted to engage with the oscillating or pivotal arm H. Suitable wires, a b c, are connected with a battery, the magnet, the screw, and arm, it being seen that when the magnets are electrically charged the armature is at- (No model.)

which is connected with the armature, draws the arm H from the screw L, thus breaking the circuit, whereby the armature is no longer attracted by the magnets, the springs G then becoming operative, so that the armature returns to its first position, setting back the dogs for engagement with another tooth of the ratchets. The armature is again quickly attracted and advances the dog, thus continuing the rotation of the ratchets, the power derived being communicated to the shaft B, whence it may be employed as desired or required.

The description thus far given applies only to the devices arranged above table A;'but two other magnets, with an. armature, pawls,

- and springs, similarly arranged and lettered,

are located under the said table and operate on said ratchets 0. Therefore, each ratchet O has two pawls operating on the same series of teeth, one above the table and the other below. Their action may be made either simultaneous or alternate, as desired. In the former case double power will be communicated to the ratchets and their shaft. In the latter case the rotation will be practically continuous, there being hardly any lost motion. These pawls keep the shaft B turning in one direction by their action of said ratchet-teeth. Theratchet is formed with two sets of teeth, .d d, pitched in reverse order, as more clearly shown by the broken away parts of Fig. 2. By this provision the direction of rotation of the shaft B may be reversed. The magnets, &c., are duplicated on each side of the shaft B, both above and below the table or platform, so that by properly arranging the connections with the batteries the motor may be operated in either direction, a feature which will be of importance for the propulsion of cars, vehicles, &c., in opposite directions.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1-. In an electric motor, an armature, a dog carried thereby, and a retracting-spring operating thereon, in combination with a ratchet-wheel engaged and turned by said dog to rotate a shaft, and circuit breaking and closing devices consisting of an oscillating arm,

and a piece between the armature and oscillating arm, which piece allows backward and forward motion of said armature, substantially as set forth. 2. In an electric motor, a ratchet-wheel on a shaft, a pawl engaging therewith, an armature carrying said pawl, and a magnet and spring which operate on said armature in opposition to each other, in combination with a slotted piece attached to said armature, an oscillating bar provided with a stud which enters the slot in said bar, and the electrical-c011- nections, whereby the circuit is closed when the armature is in one position and broken when it is in another position, substantially as set forth.

In an electric motor, a ratchet on a shalt, a pawl, whereby said ratchet is rotated, an armature which carries said pawl, and a magnet and spring which draw said armature in opposite directions, in combination with circuit breaking and closing devices consisting of a slotted piece carried by said armature, an oscillating bar provided with a stud which extends up through the slot in said piece, a screw operating against said oscillating arm, and the necessary electrical connections, substantially as set forth.

4. In an electric motor, a ratchet-wheel, in combination with a dog which operates against it above the platform or table, and another dog which operates on it below the table, in combination with the armatures, magnets, springs, and circnitclosing devices, whereby said dogs are caused to turn said shaft in the same direction, substantially as set forth.

5. In an electric motor, a ratchct-whecl, in combination with two magnets arranged on opposite sides thereof, or respectively above and below the platform or table on which said ratchet is supported, armatures attract ed by said magnets, pawls carried by said armatures, springs whereby said armatures are retracted, and circuit breaking and closing devices, the ratchet-wheel having two reverselyarranged series of teeth, and the pawls being arranged to engage therewith respect ively, so that the rotation of the ratchet-wheel and its shalt may be reversed at will, substantially as described.
